Basic prerequisites are a thorough knowledge of chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of a process in a computing device. Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. The software has to solve the mass and energy balance to find a stable operating point. The goal of a process simulation is to find optimal conditions for a process.

Verdict
The clearest difference is review sentiment: DWSIM Simulator at 57% against IITKApp's 0%. DWSIM Simulator also leads on iOS requirement (12.0 vs 15.1). IITKApp's advantage is in-app purchases (none vs 10) and update cadence (every 2 weeks vs every 6 weeks). On price, ads, monetization model and device support there is nothing between them.
